确定基于文本和字体大小的WinForms / C＃数量标签尺寸 [英] Determine Label Size based upon amount of text and font size in Winforms/C#

问题描述

我想知道是否有更好的办法处理这一问题。我想调整的标签（垂直），以容纳一定量的文本。我的标签具有固定的宽度（大约60个字符宽之前必须包），大约495像素。字体也是固定大小（12points AFAIK），但该文本是没有的。

我想要做的就是增加标签的高度时，有一个换行或文本必须换行;这个想法是，该文本是在标签完全可见。将AutoSize不起作用，因为它会增加宽度，没有高度。

当然，我可以指望换行的数量，并添加：换行* lineHeight是，然后-given，我设法把每行60个字符，只划分字符的数量，并根据需要添加尽可能多的lineHeight是像素

我在想，如果有一个更专业的方式来做到这一点。是我的做法太跛脚？

在此先感谢。

解决方案

如何 Graphics.MeasureString ，与接受一个字符串，字体过载，和最大宽度？这会返​​回一个的SizeF ，这样你就可以道道通断身高。

 使用（图形G =的createGraphics（））{
            的SizeF大小= g.MeasureString（文字，lbl.​​Font，495）;
            lbl.Height =（INT）Math.Ceiling（size.Height）;
            lbl.Text =文本;
        }
 

I'd like to know if there's a better approach to this problem. I want to resize a label (vertically) to accomodate certain amount of text. My label has a fixed width (about 60 chars wide before it must wrap), about 495 pixels. The font is also a fixed size (12points afaik), but the text is not.

What I want to do is increase the Label Height when there's a "NewLine" or the text must wrap; the idea is that the text is fully visible in the label. The AutoSize doesn't work because it will grow in width, not in height.

Of course I could count the number of NewLines and add: Newlines * LineHeight, and then -given that I manage to put 60 chars per line, just divide the number of chars and add as many LineHeight pixels as needed.

I was wondering if there was a more professional way to do it. Is my approach too "lame" ?

Thanks in advance.

解决方案

How about Graphics.MeasureString, with the overload that accepts a string, the font, and the max width? This returns a SizeF, so you can round round-off the Height.

        using(Graphics g = CreateGraphics()) {
            SizeF size = g.MeasureString(text, lbl.Font, 495);
            lbl.Height = (int) Math.Ceiling(size.Height);
            lbl.Text = text;
        }
